Yep, as I recall it was the limit of the ADT (Available Disk Table). I want
to say that the ADT was swapped in and out of core on a per-drive-basis as
needed. But the core allocated was only big enough to hold 32MEG worth of
available disk bits (per drive).

 

So, 3*5=15, 15+32=47

 

I?m just going on memory on all of this, and that?s been 20 years ago now.
Feel free to chime in here if my memory is not serving well enough.
